My VERY limited knowledge is from building an ASUSA EL84 SE kit last year. The kit's schematic doesn't show the supressor screen strapped to the cathode, but does show the signal from the input/driver tube going to the control grid, the B+ connected to the screen grid and output transformer primary winding, and the plate connected to the other side of the output transformer. I see that in a typical 2A3 circuit like the Wellborne Moondog, the signal goes to the single grid of the triode, and that the output transformer primary windings have the high voltage B+ on one end, and the high voltage B+ on the other end.Although I don't understand the details, I can now see that the implementation of the pentode in "triode" mode is not exactly parallel, at least in these examples.
Thanks for the feedback.
